51.2V 300AH Solar Lithium Energy Battery

15KWH Power Wall LiFePO4 Batteries

This 51.2V 314Ah LiFePO4 Battery is a high-capacity lithium iron phosphate energy storage battery designed for residential solar systems, commercial energy storage and off-grid backup power solutions. Featuring stable 51.2V and 314Ah large capacity, it delivers long cycle life, high safety performance and excellent deep discharge capability, perfectly matching hybrid solar inverters for home, villa, farm and industrial energy storage projects.

High-Voltage Design for Enhanced Efficiency​

Operating at 51.2V, this solar battery offers significant efficiency advantages over lower-voltage alternatives. High-voltage systems reduce current flow, minimizing energy loss through wiring and allowing for the use of thinner, more cost-effective cables. This is particularly beneficial for large solar installations where long cable runs are common, as it reduces both energy waste and installation costs. The 51.2V design also makes it compatible with a wide range of modern solar inverters and charge controllers, ensuring seamless integration into existing solar systems without the need for extensive modifications.​

Lightweight and Compact for Easy Installation​

Despite its high capacity, this lithium solar battery is surprisingly lightweight, weighing in at approximately 120kg-half the weight of a comparable lead-acid battery bank. This reduced weight makes transportation and installation much easier, especially for rooftop solar setups or locations with limited access. Its compact dimensions, typically around 80cm x 60cm x 25cm, allow for flexible placement in solar sheds, utility rooms, or other space-constrained areas. The streamlined design also means it takes up less space than multiple smaller batteries, making it a practical choice for both residential and commercial installations where space is at a premium.​

Rapid Charging to Maximize Solar Harvest​

This solar battery is designed to charge quickly, leveraging the full potential of solar panel output during peak sunlight hours. It can accept charging currents of up to 100A, allowing it to reach 80% capacity in just 4-5 hours under optimal solar conditions. This rapid charging capability ensures that the battery can fully utilize the available sunlight each day, maximizing energy storage for use during the night or periods of low solar irradiance. Its compatibility with MPPT solar charge controllers further enhances charging efficiency, as MPPT controllers optimize the power drawn from solar panels to match the battery's charging needs.
